I am getting these messages every 30 seconds or so. I searched around
and found a few other post about this problem with other devices, but no
answers to the problem. I didn't notice any of these message until I
upgrade to 4.8-RELEASE the other day. This is a dual processor machine.
It happens on all my machines that have em devices, which all happen
to be dual processor machines. I noticed that almost all the other
posts on this problem were with dual processor machines as well. Does
anyone one have a solution for this? Does anyone know what this
happens? Should I compile without SMP until this is resolved? Should I
just downgrade back to 4.7?
dmesg for one machine:
